《Linux部分》
【Linux => Debug模式】
测试：https://github.com/bombela/backward-cpp
仅头文件的库，配合#define BACKWARD_HAS_BFD 1和sudo apt install binutils-dev
可以实现Debug下精准找点。
也有apt-get install libdw-dev(#define BACKWARD_HAS_DW 1)和
apt-get install libdwarf-dev(#define BACKWARD_HAS_DWARF 1)这两个没测试。

使用方法为：
#define BACKWARD_HAS_BFD 1
#include "backward.hpp"
#include <csignal>
#include <iostream>
#include <thread>
#include <fstream>

void sig_handler(int sig)
{
    backward::StackTrace st;
    st.load_here(32);
    backward::Printer p;
    p.print(st);

    std::ofstream fs("stacktrace.log");
    p.print(st, fs); 
    fs.close();

    exit(1);
}

void th_sim()
{
    std::this_thread::sleep_for(std::chrono::seconds(5));
    // throw "Erro Auto";
    int* p = nullptr;
    *p = 33;
}

int main()
{
    signal(SIGSEGV, sig_handler);
    signal(SIGABRT, sig_handler);
    signal(SIGFPE, sig_handler);

    std::thread t(th_sim);
    std::cout << "Done" << std::endl;
    t.join();
    return 0;
}

编译链接：target_link_libraries(dmeo PRIVATE bfd dl)

《Windows部分》
【Windows => Debug模式】
#include "backward.hpp"
#include <windows.h>
使用方法：

LONG WINAPI ExceptionHandler(EXCEPTION_POINTERS* exception)
{
    backward::StackTrace st;
    st.load_from(exception->ContextRecord);
    backward::Printer p;

    // 输出到控制台
    p.print(st, std::cerr);

    // 输出到文件
    std::ofstream fs("stacktrace.log");
    p.print(st, fs);
    fs.close();

    return EXCEPTION_EXECUTE_HANDLER;   // 终止程序
}

显示初始化：backward::SignalHandling sh;而且必须在SetUnhandledExceptionFilter(ExceptionHandler); 后面。

如下：
#include <iostream>
#include <thread>
#include "backward.hpp"
#include <windows.h>

using namespace std;

LONG WINAPI ExceptionHandler(EXCEPTION_POINTERS* exception)
{
    backward::StackTrace st;
    st.load_from(exception->ContextRecord);
    backward::Printer p;

    // 输出到控制台
    p.print(st, std::cerr);

    // 输出到文件
    std::ofstream fs("stacktrace.log");
    p.print(st, fs);
    fs.close();

    return EXCEPTION_EXECUTE_HANDLER;   // 终止程序
}

void th_sim()
{
    std::this_thread::sleep_for(std::chrono::seconds(5));
    // throw "Erro Auto";
    int* p = nullptr;
    *p = 33;
}

int main()
{
    SetUnhandledExceptionFilter(ExceptionHandler);   // 注册全局异常处理
    backward::SignalHandling sh;
    // std::set_terminate(terminate_handler);
    std::thread t(th_sim);
    std::cout << "Done" << std::endl;
    t.join();
    return 0;
}

target_link_libraries(dumpdemo PRIVATE DbgHelp)
【Windows => Release模式】
实际测试，如果想生成dmp文件，就不能使用backward库（两者选一个）（不使用backward::SignalHandling sh;）。
void CreateMiniDump(EXCEPTION_POINTERS* exception) {
    HANDLE hFile = CreateFile("crash114.dmp", GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
    if (hFile == INVALID_HANDLE_VALUE) {
        return;
    };
    MINIDUMP_EXCEPTION_INFORMATION info;
    info.ThreadId = GetCurrentThreadId();
    info.ExceptionPointers = exception;
    info.ClientPointers = TRUE;
    MiniDumpWriteDump(
        GetCurrentProcess(), GetCurrentProcessId(), hFile,
        MiniDumpNormal, &info, NULL, NULL
        );
    CloseHandle(hFile);
}
使用backward堆栈信息打印有限，如下（测试代码见上方）：
Done

而使用WinDbg分析Dump文件，信息如下：
